  • A review of the beneficiation of coppercobalt

    Sulphidisation followed by flotation is the preferred beneficiation technique for oxidised coppercobalt ores • The integration of CPS systems into the flotation circuits can help minimise reagent overconsumption • Application of selective flotation can help a concentrator to produce separate oxide and sulphide concentratesOver 91 pct of the cobalt and 84 pct of the copper were recovered from cobaltite concentrate by a process that involved (1) oxidative pressure leaching, (2) jarosite precipitation, (3) ferricarsenate precipitation, (4) selective solvent extraction of copper with a mixed hydroxyomineamine extractant, (5) electrowinning of copper from recirculating acidic strip liquor, (6) selective solvent extraction of cobalt from copperRecover Cobalt & Copper from Sulfide ConcentratesFor cobalt and copper, mt2 showed a less than twofold concentration dependent upregulation at 96 hpf which became significant at 14 and 36 mg Co/L of cobalt and 25 and 61 μg Cu/L of copperConcentration dependent transcriptome responses of
